' Application July 11,1939, SerlaiNo. more 2 Claims. (cl. ass-14) This invention relates to paper receptacles of the folded blank box type, and particularly to a container for molded products such as processed cheese.

In the packaging of processed cheese, the

cheese is melted, reworked and then poured, while still warm, into a box lined with grease-proof material. The box thus serves not only as a molding receptacle for the cheese but constitutes also the merchandising package in which the cheese reaches the distributor and even the consumer.

To furnish a suitable container the box must be sumciently still to hold its shape and rigid enough to permit stacking. In addition, it must be of such a nature as to permit ready passage of heat from the molten cheese to effect the reasonably fast cooling which is important in the preservation of the quality of this food product.

Moreover, it is desirable that the package be of such a type that, when opened by removal of the top, the smoothly molded surface of the contained cheese, which is at the bottom when poured, be presented, thus requiring that what products, particularly food products, such as processed, cheese, comprising two similar tray members and a collar arranged within the side and end walls of the tray members and providing an inner wall embracing the contents, this collar and one of the tray members appropriately associated therewith being capable of use as a mold into which the contents may be introduced and molded, and the other tray providing a closure for the package, the tray member used 'as a part of the mold preferably ultimately conf stituting the top of the package, all as will be explained hereinafter more fully and finally claimed.

In the accompanyingf the invention, in the several figures or which like parts are similarly designated,

was originally the bottom of the package be,

ultimately, the top.

At present the most satisfactory container which meets these requirements is a wooden box the parts of which are nailed or stapled together.

' Buch a box, although it is suitable as a molding receptacle for the cheese, has certaindrawbacks in its use as a salable package. ,Any printing or ornamentation applied directly to it is apt to be somewhat unsightly and indistinct due to the diillculties presented by printing upon wood. Also the nailing or stapling resorted to for fastening the box parts together makes diflicult v opening of the package and removal of the molded contents without mutilation thereof. It

- will be apparent, moreover, that tools are repleted package may readily be opened without the use of tools and without mutilation of the molded contents.

The object of the present invention is, therefore, to provide such a paper container.

To this end the invention contemplates a paper receptacle or container for moldable or molded Figure l is a composite perspective view show ing the three main parts of the container in partially assembled conditiom m. 2 is a central longitudinal vertical section of a complete package of amolded product em ploying thecontainer of the invention.

Fig. 3 is a perspective view of one of the tray members and the collar assembled to provide a mold, the collar being broken awayto disclose certain structural details of the tray member.

Fig. 4 is a plan view of an appropriately cut and scored blank suitable for formation or a tray member, and

Fig. 5 is a perspective view'showing a modified form of collar. I v

The tray members l'and "la are, structurally considered, duplicates, each comprising an appropriate blank of paper board cut, scored and folded, as shown particularly in Figs. 3 and 4, to provide a closure wall 2, and side walls 3 and end walls 4 ofistanding therefrom. The end walls 4 arepreierably formed by flaps. i comprising extensionsof the closure wall 2 and overlapped upon tabs 6 carried by the side walls 8, these parts being secured together in any suitable manner as by staples or the like l.

The collar 8 is preferably formed of a strip of paper board of suilicient thickness and rigidity to provide an inner wall not subject to distortion under ordinary conditions of use, and of a width substantially equal to twice the height of the side A and end walls of the tray members. This strip collar, which portions fit snugly within the walls of the tray members, and the fourth corner may drawings, illustrating.

be formed by a butt joint ll of portions at strip ends. 4

As shown in Fig. 5, the strip from which the collar 8' is formed may be provided with V-shaped notches 8' which lie in the interior angles of three corners when the collar is folded, thus furnishing unbroken, finished outer edges for the corners.

It will be apparent from an insepction of Fig. 2, that when the two tray members I, i a are assembled 'upon the collar in telescoping relation thereto. the adjacent edges of their side and end walls will meet substantially medially of the collar, thus completely enclosing the same with its edges in intimate contact with the closure walls 2 of the tray members, thereby providing an effective seal for the contents. If desired, a sealing strip may be applied over these meeting edges of the tray members,

Preferably the container is provided with a liner ll of properly treated paper or other material suitable for the purpose.

If desired, however, all of the paper board used in the construction of the container may be of such a nature or so treated as to make it the best suited to receive and protect the product it is to contain. For example, if the contents are to be cheese, for the packaging of which the container is especially designed, the paper board may be of such a nature or so treated as to be greaseproof, or greaseand moisture-proof.

In employing the container of the invention in the packaging of cheese and other moldable.

products, the tray member l'when assembled with the collar, as shown in Fig. 1, and appro priately lined at its bottom and sides,'as shown at Ii, Fig. -2, will provide a relatively rigid mold into which the cheese I! may be poured and which may be completely filled. When the cheese solidifies upon cooling, the heat being rapidly and effectively dissipated through the enclosing paper board walls, the 'top surface II- will be covered by folding the liner in upon it, and it may thus be caused to assume an uneven contour which would detract from its appearance package having strength adequate to meet all conditions of packing, handling and use, and while including all of the advantages of the wooden box now commonly used is superior thereto and has none of its disadvantages.

Various changes and modifications are considered to be within the spirit of the invention and the scope of the following claims,

What we claim is:

l. A container for molded products, specifically processed cheese which, in molding, is poured in a hot fluid condition and solidifies by cooling including two similar tray members constituting the top and bottom of the container, a collar defining the depth of said container and assembled within said tray members in telescoping arrangement with the side and end walls thereof, said collar comprising a tubular member of solid paperboard having greater thickness than the walls of said tray members and longitudinally and laterally rigid and capable of resisting distortion in the presence of the hot fluid product, and a liner' sheet arranged within the container and normally contacting the inner surfaces of said collar and of the closure walls of said tray members, the collar and one of said tray members and said liner when assembled with the major portion of the area of the liner contacting said inner surwere this surface first exposed upon opening of the package. However, although both tray members may be printed or otherwise decorated in any desired manner, it will be noted that the tray member which forms the bottom of the mold is preferably the tray member l'which is printed or otherwise decorated in a manner suitable to constitute the ultimate top of the package, the tray member la, which mayor may not be decorated, being applied as a closure over the molded contents, as shown in Fig. 2, and being the ultimate bottom of the package. Hence, when the package is properly handled and is opened by removal, first, of the tray member i, the smoothly molded surface of the contents which was in contact with the smooth surface of the liner Ii contacting the closure wall 2 of that tray member will be exposed and will present an attractive and uniform appearance. By removing both tray members from the collar 8 the collar may be unfolded from around the molded contents and the liner il removed, thus completely freeing the contents as a cake or block.

It will be apparent that, with the tray members furnished in set-up, stapled condition, no tools are needed to assemble the parts of the container nor are tools needed to open the package.

The container provides a neat and attractive be introduced faces and its free edges extending beyond the exposed edge of the collar providing an open receptacle into which the moldable product may and constituting a rigid mold therefor with the product smoothly molded against that portion of the liner which is in contact with-the closure wall of said tray member, the free edgesof the liner being closedin upon the exposed surface of the molded product, and

the other tray member providing a means for enclosing the molded product against the infolded edge portions of the liner, the tray member which forms a part of themold ultimately serving as the top of the container, whereby when the container is opened by removing said top, the smoothly molded surface of the product covered by the liner will be exposed.

2. A container for molded products, including two similar tray members having side and end walls and closure walls connected therewith, said tray members constituting the top and bottom closure members of the container, a collar defining the'depth of the container and assembled within said tray members in-telescoping arrangement with'the side and end walls thereof and contacting their closure walls, and a liner of flexible material disposed with in said collar and preferably in contact with the walls thereof and with the closure walls of the tray members, the collar and one of said-tray members of said liner when assembled providing an open receptacle into which a moldable product may. be introduced and constituting a mold therefor, and the other tray member providing a means for closing the container and thus enclosing the molded product, the tray member which forms a part of .said mold serving ultimately as the top of the container, and the' portion of the liner in contact with the closure wall of said top-formlng tray member providing a smooth surface for the forming tray member is removed.
